Hi Everyone, could someone please assist me.

Following code:
VBA Code:
Option Explicit
Public sTimer As Boolean
Public sTimer2 As Boolean
Public sTimer3 As Boolean
Public sTimer4 As Boolean
Public sTimer5 As Boolean
Public sTimer6 As Boolean
Public sTimer7 As Boolean
Public sTimer8 As Boolean
Public sTimer9 As Boolean
Public sTimer10 As Boolean
Public wsSheet1 As Worksheet, wsTimeSummary As Worksheet

Sub Start_Timer()
        Application.OnTime Now + TimeValue("00:00:01"), "IncreamentTimer"
End Sub

Sub IncreamentTimer()
        If ThisWorkbook.Sheets("Sheet1").Range("K9").Value = "" Then ThisWorkbook.Sheets("Sheet1").Range("K9").Value = TimeValue(Now)
        If ThisWorkbook.Sheets("Sheet1").Range("K8").Value = "" Then ThisWorkbook.Sheets("Sheet1").Range("K8").Value = TimeValue(Now)
        ThisWorkbook.Sheets("Sheet1").Range("K8").Value = ThisWorkbook.Sheets("Sheet1").Range("K8").Value + TimeValue("00:00:01")
        If ThisWorkbook.Sheets("Sheet1").Range("J8").Value = "" Then ThisWorkbook.Sheets("Sheet1").Range("J8").Value = "Timer ON"
        ThisWorkbook.Sheets("Sheet1").Range("J9").Value = "Timer Start Time"
        ThisWorkbook.Sheets("Sheet1").Range("J8").Font.Color = vbGreen
        sTimer = True
End Sub

Sub PauseResume_Timer()
        If ThisWorkbook.Sheets("Sheet1").Range("K9").Value <> "" Then
                If sTimer = True Then
                        sTimer = False
                        Application.OnTime Now + TimeValue("00:00:01"), "IncreamentTimer", schedule:=False
                        ThisWorkbook.Sheets("Sheet1").Range("J8").Value = "Timer Paused"
                        ThisWorkbook.Sheets("Sheet1").Range("J8").Font.Color = vbRed
                        Application.OnTime Now + TimeValue("00:00:01"), "IncreamentTimer"
                        ThisWorkbook.Sheets("Sheet1").Range("J8").Value = "Timer Resumed"
                        ThisWorkbook.Sheets("Sheet1").Range("J8").Font.Color = vbGreen
                End If
                MsgBox "You can only click Pause/Resume button when Timer is On.", vbExclamation, "Timer Off!"
        End If
End Sub

Sub Stop_Timer()
    With ThisWorkbook
        Set wsSheet1 = .Worksheets("Sheet1")
        Set wsTimeSummary = .Worksheets("Time Summary")
    End With
    On Error Resume Next
    Application.OnTime Now + TimeValue("00:00:01"), "IncreamentTimer", schedule:=False
    If Err = 0 Then
        With wsSheet1
            .Range("L9").Value = Format(.Range("K8").Value - .Range("K9").Value, "hh:mm:ss")
            .Range("J8").Value = "Timer OFF"
            .Range("J8").Font.Color = vbBlack
        End With
        With wsTimeSummary
            .Range("E12").PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, _
                                       SkipBlanks:=False, Transpose:=False
        End With
        Application.CutCopyMode = False
        MsgBox "Timer Is currently OFF.", vbExclamation, "Timer Is OFF!"
    End If
End Sub

Sub Reset_Timer()
        ThisWorkbook.Sheets("Sheet1").Range("K8").Value = ""
        ThisWorkbook.Sheets("Sheet1").Range("K9").Value = ""
        ThisWorkbook.Sheets("Sheet1").Range("J8").Value = ""
        ThisWorkbook.Sheets("Sheet1").Range("J9").Value = ""
        ThisWorkbook.Sheets("Sheet1").Range("L9").Value = ""
End Sub

What I have noticed is when you press pause JUST before the timer wants to add another second. It crashes and gives the error in the topic.
How can I fix this? Everything else works well. It just happens now and then.
